Chemistry
- (a) Butane gas, C4H10, can burn completely in air [use O2(g) as the other reactant] to give carbon dioxide gas and water vapor. Write a balanced equation for this combustion reaction. (b) Write a balanced chemical equation for the complete combustion of C3H7BO3, a gasoline additive. The products of combustion are CO2(g), H2O(g), and B2O3(s).arrow_forwardAluminum carbide, Al4C3, reacts with water to produce methane, CH4. Al4C3(s) + 12 H2O(l) 4 Al(OH)3(s) + 3 CH4(g) 1. If 125 g of aluminum carbide is decomposed, what is the theoretical yield of methane? (a) 4.64 g (b) 13.9 g (c) 415 g (d) 154 garrow_forwardYou take 1.00 g of an aspirin tablet (a compound consisting solely of carbon, hydrogen, and oxygen), burn it in air, and collect 2.20 g CO2 and 0.400 g H2O. You know that the molar mass of aspirin is between 170 and 190 g/mol. Reacting 1 mole of salicylic acid with I mole of acetic anhydride (C4H6O3) gives you 1 mole of aspirin and 1 mole of acetic acid (C2H4O2). Use this information to determine the molecular formula of salicylic acid.arrow_forward

(b) the reaction between xenon tetrafluoride gas and water to give xenon, oxygen, and hydrogen fluoride gases. (c) the reaction between aluminum and iron(III) oxide to give aluminum oxide and iron. (d) the formation of ammonia gas from its elements. (e) the reaction between sodium chloride, sulfur dioxide gas, steam, and oxygen to give sodium sulfate and hydrogen chloride gas.arrow_forwardWhat is the molarity of a solution of strontium chloride that is prepared by dissolving 4.11 g SrCl2 in enough water to form 1.00-L solution? What is the molarity of each ion in the solution?arrow_forward4.19 How many metric tons of carbon are required to react with 7.83 metric tons of Fe2O3 according to the following reaction? 2Fe2O3+3C3CO2+4Fe How many metric tons of iron are produced?arrow_forward
